Introduction: Conservative tooth preparation has been increasingly accepted and practiced among dentist, especially when treating small sized tooth decay. This includes tunnel preparation for simple class II caries or those carious lesions located only on the proximal surface of a posterior tooth with the adjacent noncarious tooth. This study attempted to determine the practice of tooth tunnel preparations among dentists of the Palestinian Dental Association. Methods: Three hundred dentists from the Palestinian Dental Association were randomly selected and received an online questionnaire. Informed consent was also obtained. Frequency and percentage were computed for qualitative variables. Data were analyzed using SPSS Inc. Released 2009. PASW Statistics for Windows, Version 18.0. Chicago: SPSS Inc. Results: Of the 193 dentists who answered the surveys, 154 (79.8%) participants said that they were familiar with tunnel restorations. However, only 107 (55.4%) did actual cases. Most of them have been practicing dentistry for >10 years. Glass-ionomer high viscosity cement and flowable composites were usually used as filling material for this technique. Compared with class II composite restorations, tunnel restoration has more clinical success and longevity for the 74 (69.2%) of the 107 dentists, who perform the technique. Conclusion: Half of the participants with >10 years of experience perform tunnel restorations in their practice. More than half agreed that it had better clinical result than conventional class II composite restorations.
